FOUNTAIN PEN Filed June 4, 1950 nvenlor fild@ W/Ylfe 27g A Ilorney Patented June 23, 1931 UNITED STATES PATENT QFFCEy FOUNTAIN PEN- Application led June 4, 1930. Serial No. 459,137.

This invention relates to certain new and useful improvements in fountain pens, and has more particular reference' to that type of fountaln pen, the barrel of which is ardltpted to receive therein a cartridge of A primary object of this invention is therefore to provide a cartridge fountain pen having associated therewith an improved feeder to facilitate puncturing the plug closing one end of the cartridge and at the same time to provide for a smooth and steady feed of ink from the cartridge to the pen point.

A still further object of the invention is to provide a fountain pen of the above mentioned character which is com aratively simple in construction, consists of) but relatively ew parts, is inexpensive, thoroughly reliable, practical and otherwise well adapted to the purpose designed.

Other objects and advanta es of the invention will become apparent uring a study of the following description, taken in connection with the accompanying drawings, wherein:

Figure 1 is a longitudinal sectional view taken through my improved fountain pen, certain parts of the cartridge being shown broken away,

Figure 2 is a plan View of my improved feeder, s

Figure 3 is a sectional View taken through the closure plug of the cartridge.

Referring more in detail to the drawings, it will be seen that my improved fountain pen comprises a suitable barrel 5 internally threaded at one end for threaded reception of the reduced threaded'end of a stem stock 6 as at 7. At its opposite end, the barrel 5 is provided with a reduced externally threaded portion for threadedly receiving the internally threaded closure cap S) as at 8,

A cartridge 11 filled with ink of any desired color or grade is inserted in ,the barrel 5, and the cartridge l1 is closed at omx end, and its open opposite end is normally closed through the medium of a plug 13 formed of rubber or any other suitable niaterial. The closed end of the cartridge 11 50 projects beyond the' adjacent end of the barrel 5 to roject into the cap 9. The cap 9 1s provi( ed internally with a suitable coil spring 12 bearing against said closed end of the cartridge 11 for urging the same forwardly to abutl the shoulder portion of the stem stock 6 for retaining the cartridge in place against the barrel.

The plug 13 for closing the open end of the cartridge 11 is as before mentioned formed of rubber or any other suitable material to fit snugly within the open end of the cartridge. Inwardly from said open end, the cartridge 11 is pressed inwardly to provide an internal annular shoulder 16 against which,l the inner face of the plug 13 is adapted to abut for retaining the plug 13 against being pressed too` far inwardly of the cartridge 11. The plug 13 is provided with an axial bore 11 normally closed at one end of the plug by a suitable puncturable area or a diskl.

My improved feeder is designated by the reference character 17. The feeder 17 on the top thereof is provided with an ink groove 18 'extending longitudinally thereof lfrom the forward pointed end of the feeder to a point inwardly from the rear end of the feeder. At said rear end the feeder "17 is provided with a bore 20 inclining downwardly and rearwardly from the inner end of the groove 18.

A feed tube 19 has one end fitting within the groove 2O and the opposite end portion projecting beyond the corresponding end of the feeder 17. Said opposite end portion of the tube 19 is offset and at its free end is beveled to provide a penetrating point 21. Obviously' as the cartridge 11 is formed longitudinally of the barrel toward the stock 6,'the penetrating point 21 will pierce the disk or penetrable area 15 so that the offset end portion of the tube 19 will extendthrough the bore 14 to terminate inwardly of the cartridge 11 thus providing a feed passage to the groove 18. n

From the foregoing then it will be seen that as the pen in disposed in the usual pos-itiou for writing the ink will be fed from thepassage 11 through tube 19 and groove 18 to the pen point 22 which is .supported suitably on the feeder 17 between the feeder and pen stock in the usual manner.

@if course, for refilling the pen it is merely necessary to withdraw the emptied cartridge l1 andinsert in the barrel 5 a filled cartridge in substitute thereof.

Even though I have herein shown and described the preferred embodiment of my*v i invention, it is to be understood that 'the same is susceptible to changes fully comprehended b the spirit of the invention as herein descri ed and the scope of my appended claim.

Having thus described my invention, what I claim as new 1s:

In a fountain pen, a feeder formed of suitable material and adapted to be supported in the stock of the fountain pen, said feeder provided on the top face thereof with an ink groove leading inwardly from the forward end of the feeder to terminate at its inner end inwardly from the rear end of the feeder, said feeder at said rear end having an inclined bore inelining rearwardly from the inner end of said groove to the rear end of the feeder, and a tube having an end portion extending through 'said bore to terminate at the inner end of said groove, said tube havin its opposite end portion extending beyon the corresponding end of said feeder, said tube providing an ink feed leadingzfrom the barrel of the pen into said ink groove.
